It is good asking the question if there is a post-quantum theory of classical gravity. I believe it is simple. Quantum physics is in reality a theory or, to be more precise, quantum physics is in reality one self. Naturally this is scientific poppycock. What it all comes down to is this. Truth is one's very own purpose is companionship, friendship, love. Hence: Love is why the quantum. All this so self would not feel by itself. All this so self could experience companionship, friendship, love; love therefore love. You can bank on that.
